Hi Group I have a Europa XS with limited real estate on the cowl for EZ mounting of a Taxi LED. I have a Kuntzleman 3" diameter Hockey Puck and could mutilate the cowl and put a clear cover over it for a lot of work. BTW the angle coverage of Kuntzleman is 12 degrees. It's just about marginal for taxi. My build partner has a LED Headlight for his Mountain bike that is nothing short of amazing. It has a hot spot ~ 15 degree angle and incidental 25 degree coverage. It has a single large area of yellow LED that's ~ 1.2" in diameter. I was comparing light from my Volvo station wagon with H7 Halogen right only headlight, Kuntzleman and Bike Headlight. Bike headlight is whiter, brighter, better coverage than either of the other 2. The bike mfg says it measured a precise 1,000 Lumens, but for me it seems that a lot of Mfg kinda stretch the truth. Acid test going out and trying it and comparing works best for me. Amazing for 1.2". The problem is it has a control that is not conducive for aircraft. Computer controls things including an innovative sense of current at the LED. They drive it hard but control controls things great. It runs off a single Lithium battery. Being very careful to try and drive LED with a driver, worked OK sneaking up on current to match controller. When shut off upon turn on burned out LED. Anyway my question: Does anyone know of a small LED that is ~ 1.25" in diameter with wide angle and throws out incredible light? Probably needs the precise current control circuit. Can pretty EZ mount 2 on cowl. Aerosun sells a small LED but it only has a 10 degree angle. Ron P.

If you can live with 2" dia, search for 12Volt MR16 LED. The old halogen versions are used as landing lights, so should be bright enough. Projection angle can be selected from narrow spot to wide angle. If you must have the smaller dia, try searching for XML-T6 flashlight or 'headlight'. There will be some diy involved, but the smaller versions are roughly the dia you want.

Also, add a LED turn signal controller, and you have nice strobe lights.

Hi echristley What did you use for lens on your landing light? Ron P.

Ron,
Have you looked at these?

Says 1200 lumens over 8 degrees.

The light is mounted in the leading edge of the wing on a 601XL. It has a piece of plexiglass in front of it, but nothing that could be considered a "lens".

Just a little heads-up before ordering; some of the linked LEDs and driver modules are set up for household line voltage. Read the product descriptions carefully.

I love the idea for at least a taxi light. Are they bright enough to use as an actual landing light, with such a wide light pattern?

Beyond that, looking at the 110v versions is making me think about diy hangar lights. High-bay LEDs are running anywhere from $50-$200. A couple of those heatsinked to a 1 sq ft sheet of aluminum should come close to what I'd get 'pre-packaged' for $100.

I don't know if one would be enough. I put a couple of them on a piece of scrap heatsink material I had laying around, 'cause they're that cheap, draw such little power and it doesn't bother me to have a backup.
